How to specify in Dockerfile that the image is interactive?
Many of the docker run options can only be specified at the command line or via higher-level wrappers (shell scripts, Docker Compose, Kubernetes, &c.). Along with port mappings and network settings, the “interactive” and “tty” options can only be set at run time, and you can’t force these in the Dockerfile.
You can use the docker run command.
docker build -t curly .docker run -it curly curl https://stackoverflow.comThe convention is:
docker run -it IMAGE_NAME [COMMAND] [ARG...]Where [COMMAND] is curl and [ARG...] are the curl arguments, which is https://stackoverflow.com in my example.
-i enables interactive process mode. You can't specify this in the Dockerfile.-t allocates a pseudo-TTY for the container.
Are you looking for the -it option?
From the Docker documentation:
For interactive processes (like a shell), you must use -i -t together in order to allocate a tty for the container process.
So, for example you can run it like:
docker run -it IMAGE_NAME [COMMAND] [ARG...]
